Title: Improvements in the manufacture and production of wax compositions
IPC: C09G1/08
Filed: 1930-09-11
Abstract: Wax compositions are made by decomposing natural or artificial waxes consisting of or containing esters into their free components, for example by treatment with alkali solutions and subsequently decomposing the soaps, or with acids, if desired in the presence of fat-splitting agents, at atmospheric or increased pressure.  The free acids and alcohols thus formed may be mixed together in any proportions and incorporated with adulterants such as paraffin or ceresine wax, soaps, animal or vegetable oils, waxes, fats or the acids therefrom, with mineral oils, balsams or with the wax products described in Specifications 296,145, 305,552, or 308,996, [all in Class 91, Oils &c.].  The resulting compositions are used in the preparation of polishes or glazes for paper.  Solvents such as turpentine, heavy benzine, or solvent naphtha may be added, or diluents such as the lower aliphatic alcohols or benzyl alcohol.  The free acids, or their halogenated, hydroxylated or unsaturated derivatives, may be converted into salts of alkali or alkaline-earth metals, or into esters, amides, ketones, or anhydrides or into a mixed conversion product, e.g. a salt-ester as described in Specification 296,145.  The crude wax or the decomposition products obtained therefrom may be purified by bleaching, recrystallization or distillation.  Carnauba, montan or beeswax is heated at 150 DEG  C. with a dilute solution of lime or caustic soda.  The separated alcohols are removed from the mixture and are bleached by dissolving in ethyl alcohol or acetate or acetone, and treating the solution with fuller's earth or carbon. The soap residue is decomposed by mineral acid to yield free fatty acids, which may be esterified with benzyl alcohol and are then mixed with the bleached alcohols or with the alcohols derived from a different wax.  This mixture is fused with a mixture of Japan or beeswax, montan wax, stearin, and dye, turpentine oil, and not more than 12 per cent of colophony calculated on the total solids, is added to form a boot or furniture polish. The mixture may be emulsified with potassium carbonate solution to form a shoe cream. Specifications 15486/06, [Class 2, Acids and salts, Organic &c.], 255,909, [Class 121, Starch &c.], and 304,150, [Class 91, Oils &c.], also are referred to.ALSO:Wax compositions, which may be used in the preparation of a size for paper, are made by decomposing natural or artificial waxes consisting of or containing esters, into their free components, for example by treatment with alkali solutions and subsequently decomposing the soaps, or with acids, if desired in the presence of fat-splitting agents, at atmospheric or increased pressure.
